Ossification of the Posterior Longitudinal Spinal Ligament in Association with Anterior Longitudinal Ligament Ankylosing Hyperostosis: Report of Two Cases
頸椎後縱走韌帶骨化合併前縱走韌帶黏連性骨肥厚症
摘要
頸椎後縱走靭帶骨化症（以下簡稱OPLL）的報告在日本的文獻中經常可見，其發生率約在1-3%之間。在我國的文獻中則並不多見。 本院腦神經外科經歷二例OPLL合併刖縱走靭帶黏連性骨肥厚症，一例為38歲男性，在兩年內有漸進性的上肢痲痺以及酸痛，其後更伸延至下肢。最後形成四肢無力及痙攣性步伐。 經檢查及手術後屬mixed type OPLL。另一例為50歲男性，開始時只有左手大姆指及食指痲痺，繼而發生右下肢酸軟無力在一次外摔跤後症狀加劇。經診斷及手術後屬Tandem type OPLL。以上兩例於手術治療後皆獲得症狀之舒解。高解像度的CT scan對於診斷此種病例有很大之幫助。

Ossification of the posterior longitudinal ligament (OPLL) has been frequently reported in Japanese literature, but few cases have been documented in Taiwan. Two cases of OPLL combined with anterior ankylosing hyperostosis are the focus of this report. Case 1 was a 38 year-old male who reported upper limbs numbness and weakness occurring over 2 years. Later his symptoms progressed and involved all four extremities which resulted in walk with a spastic gait, CT scan showed a mixed type of OPLL. Case 2 was a 50 year-old male who had a sudden onset of left thumb and index finger numbness, and subsequent right lower limb numbness. After an accidental fall, the symptoms became worse. Again CT scan disclosed a tandem type OPLL＞ Both cases achieved satisfactory improvement after a bilateral C3 to C6 laminectomy. A high resolution CT scan proved extremely valuable in the diagnosis of OPLL, not only for indentifying the location of OPLL, but also in determining the shape and severity of it.
